“I swallowed some serious nerves and ran up, fanboyed a smidge and asked as politely as I could if she wouldn’t mind posing for a quick picture with the boys as it was their wedding day.

“She was just delightful from start to finish. She turned and smiled, strode over and gave them both the biggest hugs and wished them the greatest of health and happiness.

“It was such a wonderful surreal beautiful moment.
